When oil and gas deposits form, they leave a few witnesses in the form of tiny inclusions of fluids trapped in minerals. The objective of this project is to make these witnesses "speak" to learn more about the conditions of temperature and pressure of formation of deposits, the nature of the trapped fluids and the age of the deposits.
The purpose of this work is obviously to build relevant petroleum models to tell the geological history of the basins and the formation of reservoirs. For this, three basins in West and Central China will be the subject of studies. They are among the deepest deposits in the world and will allow us to understand how petroleum can be chemically stable in such extreme environments. This research should allow the emergence of new prospecting guides for deep deposits. It will encourage the exploitation of gas or light oil resources that emit less CO2 than coal and heavy oils.
For this, GeoRessources (UL-CNRS, France) and RIPED (PetroChina Research Institute of Petroleum Exploration & Development, China) will develop new analytical and experimental approaches to extract microquantities of fluids from inclusions and analyze them.
The post-doctoral researcher will be in charge of acquiring fluid inclusion data and coupling it to basin models. He will be involved in the development of new approaches for the chemical characterization (gas, hydrocarbons, trace elements) of their content (FT-IR, GC-MS, LA-ICPMS). Particular attention will be paid to the dating of diagenetic minerals by LA-ICPMS which will require significant calibration work. This collaborative work involves teamwork and the supervision of engineers.
The work of the post-doctoral researcher will be organized along four axes:
- Data acquisition (petrography, fluid inclusions) and modeling (PVT, basin)
- Analytical development for organic analysis, trace analysis and dating (FT-IR and / or GC-MS, LA-ICPMS)
- Engineer level training and supervision
- Writing of scientific articles
We are looking for a doctor with solid bases in diagenesis, petrography, fluid inclusions, basin modeling. An appetite for analytical development is sought in the fields of molecular and isotopic analysis. The candidate must be fluent in oral and written English. The candidate must demonstrate autonomy and appreciate teamwork.
This work is based at the UMR GeoRessources, on the premises of the Faculty of Science and Technology in Vandœuvre-lès-Nancy, under the responsibility of J. Pironon, Director of Research at the CNRS. The candidate is likely to go to China (Beijing), to the partner. Indeed, this project is the result of a cooperation contract between the CNRS and PetroChina (RIPED). The candidate will be employed by the CNRS.
This project is based on the study of deep and super deep reservoirs such as the Tarim basin, the South Junggar basin and the Sichuan basin. Their complex evolution, both diagenetic, structural and geodynamic, requires cutting-edge expertise, which the candidate must demonstrate.
Constraints and risks
